NAME

       APP - Show / manipulate APP TLV configuration

SYNOPSIS

       lldptool -t -i ethx -V APP [-c app]

       lldptool -T -i ethx -V APP [-d] app=prio,sel,pid

DESCRIPTION

       The  APP TLV is an informational TLV and will advertise the current configured application
       table. If the peer APP TLV and a local APP TLV match the same selector and protocol  field
       the local parameter is used.

ARGUMENTS

       app    Configures  a  local  application  data  field using the three parameters: priority
              (prio), selector (sel), and protocol (pid). The -d option can be provided to remove
              an entry which matches the three parameters.

Theory of Operations

       The APP TLV is an informational TLV for most end stations. It is not expected that setting
       APP data should be required. Peer data will be processed and added to the application data
       table  by  default  assuming  there  does  not  already  exist a local entry with matching
       selector and priority fields.

       By adding APP data to the application table it is available for applications,  eg  iscsid,
       to query. Applications query for a specific protocol and selector and may use this data to
       map traffic to the corresponding traffic class.

EXAMPLE & USAGE

       Configure ISCSI application for priority 4 on eth2
              lldptool -T -i eth2 -V APP app=4,2,3260

       Configure FCoE application for priority 3 on eth2
              lldptool -T -i eth2 -V APP app=3,1,35078

       Remove FCoE application for priority 3 on eth2
              lldptool -T -i eth2 -V APP -d app=3,1,35078

       Display locally configured application table on eth2
              lldptool -t -i eth2 -V APP -c app

       Display last transmitted APP TLV on eth2
              lldptool -t -i eth2 -V APP
